This week, we blew the lid off a hoax drinking app that everyone thought was totally real. We also broke down which streaming TV device is best for you, investigated that fake hoverboard, and reviewed the new Cosmos reboot. Let's look back at the best week we had this week!

Yesterday, the developers of an app called LIVR began cold-calling tech writers. The pitch was fun! A social network you can only access when you're drunk, thanks to a breathalyzer accessory. If it seems like the platonic ideal of SXSW catnip, that's because it was engineered to be exactly that. LIVR is a hoax.

With news this week that the famous Salvation Army—a haven for the homeless on the Bowery—would be replaced with an Ace hotel—a haven for hipsters—some would say it's the end of an era. But they'd be wrong. That era ended a long time ago.

When we found out that Seth MacFarlane—a man known more for fart jokes than a passion for science—was behind the reboot of Cosmos: A Personal Voyage(premiering this Sunday at 9 pm EDT on Fox), we were understandably a little concerned. Fortunately, we were also totally wrong. If the first episode is any indicator, with Neil deGrasse Tyson at the reins, the followup to Carl Sagan's otherworldly masterpiece is in very capable hands.

The SLAC National Accelerator Laboratory is one of those places that makes magic. Originally named the Stanford Linear Accelerator Center, this facility is where many modern discoveries about how matter works were made. Six researchers have earned Nobel prizes for their work at SLAC. It's also where the first website in North America was built.

So you want to stream stuff to your TV. These days you have plenty of options, but which of them is best? After Roku announced its upcoming $50 HDMI-ready streaming stick, we put this chart together to show you how it stacks up to the competition.

Back during the no-carb diet craze of the early 2000s, I joked that I wanted to try a diet consisting of nothing but carbs and lipids. I would call it the Fatkins Diet. Guess what? I just did exactly that. I ate ice cream, and only ice cream, for four days straight. Yes, it's the world's first Ice Cream Cleanse, and no, I didn't just make it up.

You can learn the basics of lock picking from a GIF, but for a more nuanced look at the techniques required to actually get a lock open without the key, check out NightHawkInLight's latest tutorial where he uses nothing but a pair of strategically bent hairpins in the process.

It's been almost three years since a gunman detonated a bomb in Oslo and then stormed a small summer camp off the coast of Norway, killing 77 people and cementing a record as the worst mass shooting in modern memory. This month, the country revealed plans for a memorial to the tragedy—and it's beautiful.

They're being targeted as harbingers of evil as their buses chug through otherwise inaccessible, gentrified neighborhoods. Now San Francisco's tech workers are fighting back with a networking event called the Tech Workers Against Displacement Happy Hour, that, in addition to sounding like a whole lot of fun, hopes to gather attendees who are "sick of being blamed for SF's housing crisis."

In 1989 the director of Back to the Future II went on TV and declared that hoverboards were real. "They've been around for years, it's just that parents' groups have not let the toy manufacturers make them," Robert Zemeckis insisted. "But we got our hands on some and we put them in the movie."
